I've had a funny relationship with math my whole life. I loved it as a kid and through high school. I even considered majoring in math -- that is, until I got to college calculus and math went beyond 3 dimensions. I quickly detoured to liberal arts, then law, then art, thinking my math days were behind me.
But then came fused glass. Not only do you have to make calculations to figure out how much heat you need depending on the mass of glass you are firing, but you also need to do a lot of basic arithmetic in cutting glass to fit your design. Here's an example.
I created a couple of pieces I thought would be a great accent in a sculpture. I selected the mold I wanted to use - a large S-curve - and measured its dimensions. I cut a piece of paper to those dimensions and laid the accent pieces in where I wanted them, tracing around them (the blank rectangles in the photo below).
The next step was to cut rectangles to fit in with the accent pieces. I had two goals: to cut the fewest pieces of glass possible, and to cut different configurations for each of the two layers, so the glass would overlap the seams, making them less visible.
Note my paper with measurements close at hand while I was cutting:
